    What to do if my Pentair NOCCHI CM motor runs but doesn't pump liquid?

      If the motor of your Pentair Water Pump runs but no liquid is being pumped, it could be due to a couple of reasons. First, the pump might be sucking air. Ensure that the joints are airtight, the liquid level hasn't dropped below the minimum priming level, and the foot valve is airtight and not blocked. Second, the pump may be rotating in the wrong direction; if so, reset the direction of rotation.

    Why does my Pentair NOCCHI CM Water Pump stop after running for a short time?

      Your Pentair Water Pump might be stopping due to the thermal motor circuit breaker tripping. This could be because the power supply doesn't match the nameplate data – check the voltage on the power supply cable leads. Alternatively, a solid object might be blocking the impellers, requiring you to dismantle and clean the pump. Lastly, the liquid might be too thick, suggesting the need to change the type of pump.

      If your Pentair Water Pump isn't pumping water and the motor isn't running, here are a few things to check: * Verify that there is power present. * See if the motor protection has tripped; if so, identify the cause and reset the switch, waiting for the system to cool down if the thermal circuit breaker tripped. * A defective condenser could be the issue, in which case, replace it. * Lastly, the shaft might be blocked; determine the cause and unblock the pump.
